Description
In the Linux kernel, the following vulnerability has been resolved:
w1: fix WARNING after calling w1_process()
I got the following WARNING message while removing driver(ds2482):
------------[ cut here ]------------

The state of task is set to TASK_INTERRUPTIBLE in loop in w1_process(),
set it to TASK_RUNNING when it breaks out of the loop to avoid the
